核心代码如下:

    mLocalRender.setVisibility(View.GONE);    mRemoteRender.setVisibility(View.GONE);    mLocalRenderLayout.removeView(mLocalRender);    mRemoteRenderLayout.removeView(mRemoteRender);    mLocalRender.setZOrderMediaOverlay(mLocalPreview);    mRemoteRender.setZOrderMediaOverlay(!mLocalPreview);    mLocalRenderLayout.addView(mLocalRender, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT));    mRemoteRenderLayout.addView(mRemoteRender, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT));    mLocalRender.setVisibility(View.VISIBLE);    mRemoteRender.setVisibility(View.VISIBLE);
